getUserMedia use audio only will be closed by itself in few seconds on mac chrome

The same code bellow, you can run it in chrome console on both windows OS and Mac OS.

navigator.mediaDevices.getUserMedia({audio: true})

On my Mac, it will be closed in a few seconds.

On my Windows, it works fine.

In my project, there are no any code changed, it works fine in the past few months... but these days, it's broken on mac chrome...

See sample code here Sample code

Steps:

  1. Click on show button, you can get undefined

  2. Click on start button.

  3. After Media started, click show button, you can get a MediaStream object with active: true. And you can see the red circle on chrome tab.

  4. Wait a few seconds(maybe 10s), you can see the red circle on chrome tab will missing, then click the show button, you can get a MediaStream object with active: false.

BTW, this issue is on mac chrome, windows chrome is correct.

  • Not sure, maybe the OS and chrome issue.

    I upgrade mac os from 10.12.5 -> 10.12.6, and chrome from 61 -> 62, issue solved.
